Solutions for CORROSIVE ENVIRONMENTS. Our control valves also play an important role in the extraction of metals. Where mechanical separation processes no longer suffice, the metal is leached with the help of chemicals. To do so, ground ore is mixed with different liquids. Usually, the created slurries are highly abrasive and corrosive.

Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides.
